Refactor CopyAttributeOut{CSV,Text}() to use a callback in COPY TO
These routines are used by the text and CSV formats to send an output
representation of a string, applying quotes if required. This is
similar to 95fb5b49024a, reducing the number of "if" branches that need
to be checked on a per-row basis when sending representation of fields
in text or CSV mode.
While on it, this simplifies the signature of CopyAttributeOutCSV() as
it is possible to know that an attribute is alone on a line thanks to
CopyToState. Headers should not use quotes, even if forced at query
level.
